Description
Technical Field
The utility model relates to the field of cigarette manufacturing, in particular to a fault detection device for a conveying part of a drying channel of a packaging machine.
Background
During the working process of a packaging machine (such as YB25 type), after aluminum foil paper, cigarette groups and label paper are folded and packaged by a first wheel, a second wheel, a third wheel and a fourth wheel, the cigarette groups are pushed out of the fourth wheel by a fourth wheel vertical pushing rod and enter a seal forming folding channel. When the tobacco bale is pushed out by the transverse bale pushing rod, the sealing labels with the glue are driven to pass through the F air suction arm and then are pasted through the two sealing label forming blocks, the tobacco receiving rod protects the sealing labels from moving into the drying channel, the tobacco bale in the sealing channel is detected through diffuse reflection, the top and the bottom of the tobacco bale are controlled to rotate by a station, and the tobacco bale is pushed by the vertical bale pushing rod to move by a station. After the cigarette packet passes through the F air suction arm, the seal is not completely adhered to the cigarette packet at the moment, the cigarette packet needs to be tightly arranged and shaped in the drying output channel, and the side surface of the cigarette packet can also be subjected to heat sealing.
When the smoke-free coatings in the sealing channel are transversely pushed out, the quantity of light reflected by the optical fiber sensor of the sealing channel is lower than the set threshold value of the amplifier, the packer controller defaults to no cigarette packet, the electromagnet is separated from the belt driving device, and the belts on the two sides of the drying channel do not clamp the cigarette packet any more and move one cigarette packet width towards the five-wheel outlet direction.
By the aid of the detection logic relation between the electromagnets and the cigarette packets, when a detection threshold value of the cigarette packets is low, the controller easily mistakenly judges that the cigarette packets pass through the drying channel, the electromagnets are triggered to connect the power device with the belt driving device, the belt rotates to drive the cigarette packets to move for one station, and at the moment, the drying channel is lack of packets, so that the cigarette packet seal is poor in fixation, and the cigarette packet seal is prone to being inclined and long; and when the tobacco bale detection threshold value was higher, the controller thinks easily by mistake that there is not the tobacco bale in the dry passageway, trigger the electro-magnet and throw off the connection, the belt is no longer rotatory, tobacco bale no longer moves in the dry passageway, the tobacco bale quantity of dry passageway will increase this moment, extrusion force between the tobacco bale increases, produce "many packages" problem (in addition, because electro-magnet action time is along with service life slows down, the tobacco bale motion is unmatched with the operation of pushing away the package pole, also can produce many packages circumstances), lead to the local deformation to appear in the tobacco bale bottom, local damage etc. appear in the tobacco bale facing slip. The above situation may generate more waste smoke packets and may hide more quality problem points.
The practice of a production field shows that the reason for the phenomenon of multiple packets or few packets is not only related to the signal threshold of the cigarette packet, but also related to other factors such as a conveying belt, a tension pulley, an electromagnetic threshold and the like, so that the problem is difficult to be reliably locked to the root of the problem, and therefore, at present, the cigarette packet in the drying channel is manually intervened mainly by means of manual self-checking, for example, the cigarette packet is added or taken out, so that the proper extrusion force between the cigarette packets in the drying channel can be kept, but the mode not only consumes manpower and is easy to generate errors, but also is difficult to meet the real requirement of the production field.

a plurality of tooth parts 32 are formed on the edge of the detection disc 3, and the first diffuse reflection optical fiber sensor 1 is opposite to the tooth parts 32 and is used for detecting a belt movement angle signal;
the cigarette packet detector 4 is used for detecting a first cigarette packet existence signal at the tag forming channel;

the first diffuse reflection optical fiber sensor 1, the second diffuse reflection optical fiber sensor 2 and the cigarette packet detector 4 are respectively in electric signal connection with an original machine controller.
Further, the cigarette packet detector 4 adopts a diffuse reflection optical fiber sensor, and on this basis, the detection device further comprises an optical fiber amplifier, wherein an electrical signal of the optical fiber amplifier is connected between the cigarette packet detector 4 and the original machine controller.

The operation of the device is schematically described in the following with reference to the embodiments: the belt movement angle signal, the first cigarette packet existence signal and the second cigarette packet existence signal can represent whether the cigarette packet is abnormal or not in the process of conveying to the drying channel. Under normal conditions, when first tobacco bale existence signal was the high level, the detection dish can be driven and rotate certain angle, and a belt motion angle signal can receive a N high level signal (produced by the facula), and second tobacco bale existence signal is the high level afterwards, explains that the tobacco bale normally gets into in the dry passageway.
If the signal of the first cigarette packet is high level, the signal of the second cigarette packet is high level, but no belt movement angle signal exists, the electromagnetic valve is indicated to have a problem and needs to be replaced; similarly, when the signal of the first cigarette packet is at a high level and the signal of the second cigarette packet is at a high level, the signal with the motion angle is delayed, which indicates that the electromagnetic valve is slow in action and needs to be maintained.

And when the signal of the existence of the first cigarette packet is high level, the signal of the movement angle of the belt is not 0, and the signal of the existence of the second cigarette packet is also high level, but the condition of more packets or less packets still occurs in the drying channel, which indicates that the conveying belt needs to be replaced and/or the tension wheel needs to be adjusted.
